Quels matériels acheter ? 🔭 (Lastrophoto Ep 1)

Hello everyone and welcome to the first episode on astrophotography one day looking at the starry sky, you you may have said if it was possible to photograph the Milky Way and other celestial objects well yes and I will explain that to you in three episodes but above all else here is a little summary the first episode will talk about the equipment to buy the second will explain how set up your equipment and photograph an object and the last one will show you how to process your photos once this little summary is done we will start Light pollution In Astrophotography, there is a phenomenon that spoils most photos in the city we call it light pollution Basically the light of a city obscures most of the interesting objects explain that I will give you a little diagram Here is the sky without light pollution we can observe a multitude of stars and the Milky Way But now we’ll add the pollution luminous we can see that the light of the city erased the milky way and many stars that’s why we have to move away from cities to know if our garden is exposed to light pollution we will use a pollution card for example I will choose a random region, Alsace! then I click on a place. As you see it shows me a bortle of 4 for example at paris the bortle is 8 and the sky looks like this but if i go right in the middle of chili the bortle is 1, and the sky looks like this this scale allows calculate the light pollution and i advise you to watch it before to buy a telescope The targets now we are going to find our targets. In the universe there are 5 great types of objects to photograph… first is the milky way for this one all you need is a camera and a mount or a tripod the second are the planets, for that here you will need a telescope with a powerful zoom. The third are the clusters you can photograph them with a simple des tele - lenses and a mount but the telescope is recommended.

The fourth 02:05 - are the nebulae, you can photograph with a telephoto lens or telescope it depends on your preferences and your budget. And the last are the galaxies, it is recommended to photograph with a telescope because the most galaxies are small and therefore you will need a device capable of zooming! The two essential tools During a sky photograph several tools are essential the imager and the mount… for the imager you can use a simple device photo opportunities to start making beautiful photos and for the frame it’s more complicated first of all you need a frame equatorial roughly a mount that goes follow the sky thanks to the alignment of the polar star in a viewfinder. Then the mount can withstand a certain weight for example an eq3-2 from skywatcher can support a maximum weight of 5kg so to have a perfect follow-up your device or telescope must not not exceed 5 kg. So it depends on your preferences if you prefer to do wide field as photo of the track very diffuse nebulae, you can opt for the frame and the telephoto lens.

But if you prefer visually observed and 03:12 - take pictures of smaller objects I highly recommend the telescope and mount. otherwise if you want to buy a telescope there are several types… The newton which presents a mirror of crested and which bring out the image on the tube side. The cassegrain who unlike the newton hold the secondary mirror on a lens that allows you to remove the egrets on Pictures. and glasses chromatic which does not present mirror but what do the results do much cleaner, to begin with and not not spend the ass skin i you recommend the newton it cheap and gives good results.

And don’t forget what matters in a 03:52 - telescope is the opening if the telescope has an aperture of 150 mm you will have much less detail than a 200 mm. Here you know now the rules that govern laws of astrophoto. Here we are going to take an example. of a rather good telescope for astrophotography… We will take a mount that can support a fairly heavy weight for example a Neq-5, it can support up to 10 kg but 7 kg is recommended in photo. Then for the tube we can take a ¹⁵⁰⁄₇₅₀ it is much less powerful than a ²⁰⁰⁄₁₀₀₀ but we have no limit of weight unlike the ²⁰⁰⁄₁₀₀₀. To obtain such good results we will just have to take more breaks long and voila in my opinion it is the cheapest telescope that exists.

and if you prefer to do 04:39 - more beautiful photos you can choose for an Eq6 and a ²⁰⁰⁄₁₀₀₀, which costs almost 1700 euros here it is over for this first episode on astrophotography thank you for having it watch and do not hesitate to share it and like it and therefore the next one episode will explain how to set up your equipment and how to photograph an object see you soon.
